Title:
DEVICE AND METHOD FOR MANUFACTURING ELLIPTICAL METAL CARRIER FOR CATALYST DEVICE
Document Type and Number:
Japanese Patent JP3208030
Kind Code:
B2
Abstract:
PURPOSE: To provide a metal carrier for a catalyst device of constant shape forming a honeycomb body of elliptical shape to be manufactured easily which contains no resistant matters to exhaust gas flow.
CONSTITUTION: Three projected sections (a) and two recessed sections (b) are formed on one sides 11 of two core tube plates 10, almost rectangular and of thin plate shape. Shaft necks 13 formed on opposite sides 12 are supported by a bearing 14, and the distance (c) between the bottom sides of the recessed sections is formed into the size for storing the width (d) of a plate material, and core tube plates 10 are set rotatably. The end edge (e) of a corrugated material 1 and a plane plater material 2 laminated together are passed through the projected sections (a) and recessed sections (b) to form winding start section of the plate material, and the end edges are wound on the plate material by rotating the core tube plates 10, and then the core tube plates 10 are drawn out from the left and right to form an elliptical honeycomb body 3. For varying the flattening rate of ellipsis, the dimensions (f) of the recessed and projected sections 15 are adjusted.
